i think i have read enough to get the just of what everyone is feeling...

so heres my 2 cents
i have the privilege of being the father of 2 kids, a 6 year old daughter (born 3years before i married her mother) and soon to be 1 year old daughter. My wife and i never planned to have kids let alone so young, but i believe that we all have a destiny and to all the parents who are feeling frustrated at times, i always try and remember, YOU CANNOT CHANGE THE DIRECTION OF THE WIND, BUT YOU CAN ALWAYS ADJUST YOUR SAIL. This is even more relevant to those who wished they worked abroad
I turned 27 this year, completed my honours degree (studied between feeds and nappy changes) and purchased our 2nd property this year and still receive new job offers weekly (which i weigh against how it will affect my responsibility to my family), i have met my family's primary need for security already, everything else is "gravy".
Its stressful, believe me, but without my wife and kids all my achievements wouldnt mean a thing!! Your sense of purpose should've been clear when you knew you were going to be a parent. The "wants" will always be there and change as we mature and our priorities change, always remember that when i "think of what life would be like if..."
You can still achieve all your dreams and still be a parent, you just have the added bonus of sharing it with family who couldnt care less even if you didnt have a pair of shoelaces to all those who think possessions and "things" are important.
